SSR Checker
The SSR Checker tool loads a given URL twice using a headless Chromium browser, once with JavaScript disabled to inspect server-rendered HTML and once with JavaScript enabled. It presents a side-by-side comparison to help developers and SEO professionals identify client-rendered content sections, detect rendering discrepancies, and evaluate potential search engine indexing issues or performance bottlenecks on frameworks like React, Vue, and Angular.
